Although Li Dingguo is now a member of the government army, he has not forgotten his marching skills.

Under his command, nearly 10,000 cavalrymen formed a long column and marched at full speed from north to south along the Great Wall.

Generally speaking, there are sentries near the Great Wall.

When they found any trace of the enemy, they would report it immediately, and the nearby cities would gather the corresponding number of troops based on the information from the sentries to prepare for defense against the enemy.

Who was the Liaodong Great Wall defending against?

During the Ming Dynasty, the Liaodong Great Wall was used to defend against the Liaodong Mongols.

After the Jiannu occupied Liaodong, they intermarried with the nearby Mongols on a large scale.

Not only were the Mongols incorporated into the Eight Banners, they were also allowed to participate in internal affairs.

Under the influence of this policy, the Liaodong Mongols soon became one with the Jiannu.

The Liaodong Great Wall became useless.

The Jiannu had few sentries on the Liaodong Great Wall. In order to deal with the Ping Liao army, Jirgalang mobilized all the troops he could.

So, this place became a vacuum zone.

Li Dingguo didn't know this road at first.

He originally wanted to use the strategy of making a feint to the east and attacking in the west to return to the west bank of the Liao River, but the surrendered Jiannu soldiers told him the news.

Li Dingguo first sent light cavalry to conduct reconnaissance, and after confirming that everything was correct, he immediately led his troops south.

However, doing so is also very risky.

Once encountering the Jiannu, his army will not be able to deploy head-on, let alone exert its true strength.

The afternoon of May 18th.

When Man Dahai left Haizhou Wei and arrived near Liaoyang, Li Dingguo had already arrived at Dongchang Fort smoothly.

Dongchang Fort is less than fifty miles away from Haizhou Wei.

The two missed each other perfectly.

"General," the surrendered Jiannu general said to Li Dingguo, "Dongchang Fort is adjacent to Sancha River to the west. After crossing Sancha River, you will reach Daliao River. After crossing Daliao River, you will reach Xining Fort, which you passed by earlier."

"Oh?" Li Dingguo stopped his horse.

Seeing this, the army behind him also slowly stopped.

Li Dingguo stared at the surrendered Jiannu general and asked, "This place shouldn't be far from Haizhouwei, right?"

"Not far, less than fifty miles."

"If we march quickly now, can we reach Haizhou Wei before nightfall?" Li Dingguo asked again.

"This..." The surrendered general of Jiannu pondered for a while and said slowly: "It's barely possible, but the situation in Haizhou Weicheng is unclear. If we go there rashly, we may encounter the main force of the Eight Banners."

"Whether there are Eight Banners main forces, we can only know after trying." Li Dingguo smiled and looked behind him: "Gao Wengui."

"I will be here!"

"You lead two thousand cavalrymen disguised as Eight Banners soldiers, and use Kong Youde's seal to knock on the gate of Haizhouwei. If the Jiannu are not discovered, you can take the opportunity to enter the city. You can kill fewer people, but all the food and grass in the city must be burned!"

"I will obey your orders."

Gao Wengui grinned and led his troops away.
